The back of the reinforcement frame 10 is provided with a placement groove for use with the locking plate 23. The design of the placement groove can place the locking plate 23 so as to provide the locking plate 23 with sufficient space for withdrawal.
[0019] Working principle: under the elastic force of the first spring 9 and the second spring 13, the slide plate 6 can maintain an external extension state, and the pressure plate 12 can maintain an upward swinging state at one end, and the height of the swinging end of the pressure plate 12 is slightly higher than the highest point of the protruding part of the top of the harvester body. If the height of the height-limiting structure is low, the height-limiting structure is not limited to the height-limiting frame, but all structures at a high place that can collide with the top of the harvester, such as the bottom of some bridges or culverts, and the lower position here is a position that is difficult for the driver to reach, that is, the top position of the front of the top cover body 1. At this time, the reinforcement frame 10 will collide with the height-limiting structure in advance and move backward under the action of the impact force, thereby driving the first displacement sensor 11 to move backward synchronously, and continuously shortening the distance between it and the positioning plate 24. The first displacement sensor 11 can monitor the displacement distance in real time, and when the slide plate 6 moves under force, the second displacement sensor 17 will be driven to move synchronously with the cooperation of the movable frame 14 and the movable frame 16. If the height of the height-limiting structure is between the top of the top cover body 1 and the protruding part of the top of the harvester body, the height-limiting structure will hit the pressure plate 12, and drive the pressure plate 12 to swing downward, and compress the first spring 9. At this time, with the assistance of the activity of the movable frame 14, the movable frame 16 and the second displacement sensor 17 can be driven to move backward synchronously, and the distance between the second displacement sensor 17 and the back of the inner cavity of the strip box 15 is continuously shortened. The second displacement sensor 17 can monitor the displacement distance in real time, and the pressure plate 12 is When the first displacement sensor 11 and the second displacement sensor 17 are used together, the movement and swinging state of the reinforcement frame 10 and the pressure plate 12 can be monitored in time. When the distance between the first displacement sensor 11 and the second displacement sensor 17 is set to a preset value, the alarm 21 can be turned on by the controller 34 in time to warn the driver of abnormality. At the same time, the small electric push rod 22 is turned on by the controller 34. At this time, the small electric push rod 22 can drive the locking plate 23 to move until the locking plate 23 is completely separated from the T-box 19 and the telescopic frame 20, so that the T-box 19 and the telescopic frame 20 can be quickly released. The frame 20 and the alarm 21 are in a locked state. At this time, under the action of gravity, the alarm 21 can quickly fall from both sides of the top cover body 1 to the windshield at the bottom of the top cover body 1, thereby expanding the warning range and facilitating the driver to observe the alarm in time, so that the driver can brake in time to avoid danger, and can effectively prevent the top cover body 1 or the top protruding part of the harvester from hitting the height limit structure. The fixing bolts 3 can be used to quickly disassemble and assemble the I-frame 2, and cooperate with the third spring 28, the fourth spring 32, the U-frame 25, the limit frame 26, the square socket 29, the auxiliary socket 33, the second T-bar 31 and the T-column 27, so that the pressure plate 12 can autonomously change the swing amplitude according to the height of the protruding part on the top of the harvester body, so that the device can be adapted to different harvester models.
[0020] However, as is well known to those skilled in the art, the working principles and wiring methods of the first displacement sensor 11, the second displacement sensor 17, the alarm 21, the small electric push rod 22 and the controller 34 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.
